Hi Vanessa,
You have to understand the key concept of user pools in IMS Bench SIPp. The
whole benchmark is very "user centric" with the test system acting as a user
population. In order to be able to correctly emulate user behaviours, the
system must keep track of the user state in some way (so as to, for example,
place calls to registered or non registered users in the proportion specified
by the scenario execution ratios; or to only deregister users that were
previously registered). It is actually the scenarios that have to maintain this
user state because only the scenarios know what they intend to do (SIPp has no
knowledge of "being registered" or anything like that so it remains fully
flexible). The way IMS Bench SIPp provides support for this to the scenario
designer is by means of those user pools. You can define yourself what state
(or possibly combination of states) a pool represent. In standard scenarios,
pool 0 is the pool of non-registered users. Hence the ims_reg scenario takes
users from this pool as you can see in the following scenario fragment (from
beginning of ims_reg scenario):
<nop>
<action>
<assign_user pool="0" scheme="rand_uni"/> <!-- 'Unregistered' user -->
<move_user pool="1"/> <!-- Registration ongoing -->
</action>
</nop>
It also puts the user into a temporary pool, pool 1, in order to avoid starting
two registrations in parallel for the same user. Because an instance of the
ims_reg scenario moves the user into pool 1 as soon as it has selected him to
perform a registration, the same user cannot be picked again by another
instance of ims_reg scenario because the scenario always takes its user from
pool 0, not pool 1.
I hope I'm making sense here. This is also explained in the IMS Bench SIPp
online documentation
(http://sipp.sourceforge.net/ims_bench/reference.html#User+oriented+mode) but I
understand there is a lot of information to digest there.
So the error
2008-10-07 14:27:33.624: User pool id[0] is empty -> Quitting!.
means that the ims_reg scenario that was trying to run could not find any user
in pool 0. Without a user, it can't run because its purpose is to register the
user. If this happens right away when you start your test, then it probably
means the file you specify by means of the -user_inf SIPp command line
attribute is not correct. In this file, the first column indicates the initial
pool in which the user is put. If you start by a registration phase (as in the
standard benchmark), then all users should initially live in pool 0.
If it happens after some time of correct execution, then it probably means you
did not provide enough users in order to run the registration phase at the
specified rate and for the specified duration. (e.g. 100 registrations/s for a
120 s registration phase requires at least 12000 users in the -user_inf
specified file; and if you keep doing registrations together with other
scenarios after the initial registration phase, then you should have slightly
more users in order to avoid running out of users in pool 0 in the subsequent
phases).

David,
sorry for my constant questions :S I found an error in usuarios.csv. I create
users.inf as I read in documentation, now I'm registered with the proxy but the
execution don't continue with INVITE message. The error log said:
Epi:/home/ims1/sipp_3_1_ims_bench/ims_bench # cat 20794_errors.log
sipp: The following events occured:

2008-10-07 14:27:33.658: final cleanup.
My document ims_reg is equal to the IMS bench ims_reg.xml, I add the line
"[authentication [EMAIL PROTECTED] password=[field4] challenge_from="u2"
challenge_type=401]" for the none, but I don't understand what is the message
"2008-10-07 14:27:33.624: User pool id[0] is empty -> Quitting!."
Thanks

As I read in the documentation, I execute manager.xml then sipp comand and

I attach the screens, usuarios.csv, ims_reg.xml (because I changed one line in
REGISTER authentication) and log_sipp.

Could you please send screen output and log files from manager and sipp ?
Note that, as described in
http://sipp.sourceforge.net/ims_bench/reference.html#Running, once all desired
components are started (and you see they all connected to the manager) you
should press the 'e' key in the manager console. (alternatively, you can
configured the expected number of SIPp instances and have the manager start
automatically once they all have connected).

Subject: [Sipp-users] Run basic scenarios IMS bench.
Hi all,
I'm trying to run the basic scenarios in IMS Bench which appears in a folder
called scen when you install it all.
I execute ./manager - f manager.xml and then the comand: ./sipp
ip_core_ims:4060 -rmctrl ip_manager_machine:5000 -user_inf scen/usuarios.csv -i
ip_manager_machine -p 5000
But the problem is that anything happen... Can anybody tell me how to test the
basic scripts please? I think that understanding the basic funcionality I can
create my own scenarios
Best regards
